Resource	Grade Level	Media Type
Birth of a Supernova, Type Ia In this interactive activity from NOVA Online, learn about a type of exploding star — a Type Ia supernova — that is so bright that astronomers can measure the distance to the galaxy in which it resides, and even learn which elements make up the star.	6-12	Flash Interactive
Birth of a Supernova, Type II In this interactive activity from NOVA Online, learn about a type of exploding star — a Type II supernova — that is so large it has a mass 10 times greater than the mass of our Sun.	6-12	Flash Interactive
Evidence for the Big Bang Theory This video segment adapted from NOVA tells the story of two scientists who inadvertently discovered microwave radiation that is now believed to be heat left over from the Big Bang.	9-12	QuickTime Video
Gravity and the Expanding Universe This video segment, adapted from NOVA, traces the evolving history of theories about gravity and a force that may oppose it, along with our understanding of the impact of both of these forces on our expanding universe.	6-12	QuickTime Video
How Big Is Our Universe? This interactive resource from Harvard Smithsonian Center for Astrophysics uses images and activities to understand the scope and scale of our universe. Featured are technologies used by generations of explorers.	3-12	HTML Interactive
How Big Is the Universe? In this media-rich essay from the NOVA Web site, astronomer Brent Tully of the University of Hawaiʻi walks you through the latest scientific theories about the size of the universe.	6-12	HTML Document
Hubble's Expanding Universe This adapted video segment, using footage from NOVA and NASA, examines Edwin Hubble's work and how his findings laid the foundation for the Big Bang theory.	6-12	QuickTime Video
Hubble Telescope: Looking Deep This video segment adapted from the Space Telescope Science Institute shows what the Hubble telescope found when it stared at a single, nearly empty spot in the sky for 10 days in 1995. The unexpected result was a picture of a multitude of galaxies stretching into the distance.	6-12	QuickTime Video
Monster Black Hole in Galaxy M84 This animation by Thomas Goertel of the Space Telescope Science Institute is an artist's conception of a spiral galaxy harboring a super-massive black hole. Observe how the material rotates faster the closer it is to the nucleus.	6-12	QuickTime Video
Relativity and the Cosmos This illustrated essay from the NOVA Web site introduces the basic concepts of Einstein's General Theory of Relativity and what we know about cosmology as a result.	6-12	HTML Document
Stellar Velocity: The Doppler Effect This interactive activity from the NOVA Web site illustrates the Doppler effect and shows how it applies to measuring the direction and speed of stellar objects.	6-12	Flash Interactive
WMAP: "Baby Picture" of the Universe View the Wilkinson Microwave Anisotropy Probe (WMAP) image from NASA to see the first detailed map of the oldest light in the universe, from 379,000 years after the Big Bang, over 13 billion years ago. A second image offers a visual timeline to put the WMAP image in perspective.	9-12	JPEG Image
